I've read other topics about my problem but noone refers to it directly. I'm just so big noob that I cannot understand many of advices posted (and my English is not so good as well). I've tried to install Qwt-5.2.0 on WinXP SP3 using MinGW compiler. I had directory with Qwt on my desktop and I used Qt Command Prompt to build (at least that was my plan). I wrote qmake qwt.pro and the Makefile was created. Then i wrote mingw32-make and make has been working for about a minute. Although, when I go into examples directory there are only projects without any build. Nvm because I don't need the examples but the worse thing is I don't know what I should do now. Copy directory somewhere? I just want to see widgets in QtCreator. Please help me and don't delete my topic, if something is wrong I can correct the mistakes (I suppose I can). Thanks.
